PUMP.

SPECIFICATION forming part of Letters Patent No. 294,210, dated February26, 1884.-.

Application filed April 1853. (Xo model.) l

all whom, may ceiwczt.-

.Be it known that I, J osnrn: W'. DoUcLAs, a citizen of the UnitedStates, residing at Middletown, in the` county of Middlesex and St-ateof Connecticut, have invented new and useful Improvements in Pumps, ofwhich t-he following is a specification.

Myinvention relates to that class of attachments for pumps whereby theWater raised by io the action of the plunger may either be dischargedthrough the nozzle or `be diverted through a branch p ipe and deliveredat any desired point at pleasure.

The object of my invention is to improve such class of pumps by passingthe plungerrod ofthe pump through both of the tva-ten Ways ofthethree-way cock, said Waterlivays forming eontinuations et' theWater-pipe leading to the Water stratum. This I accomplish 2O in themanner and by the means hereinafter described and claimed, andillustrated in the accompanying drawings, in which Figure l is a centrallongitudinal section taken through a pump of ordinary construev tion,having the tube, together with the cylinder and plunger, attached. Fig.2 is a central vertical section ot' Fig. 3. Fig.3 is a side elevation ofthe attachment shown in section in Fig. 2. Fig. 4t is a central verticalsection, 3o showing a further modification; and Fig. 5 a detachedsectional view, showingv modiiied means for operating the three-wayvalve.

A in said drawings designates the pump, which may be ol' any ordinarypattern7 hav- 3 5 ing a dischargespout, B, and handle C. The latter islinked directly to the plunger-rod D. which passes down through the openbody of the pump to the point Where it unites with the plunger E. Theseparts do not differ in 4o. any respect from thewell-known constructionsin ordinary use.

F indicates a short section, which is interposed in the pump-tube at anysuitable point above the plungerE and the chamber or cylinder in whichit moves. This part F is provided with suitable fittings, whereby it maybe threaded upon the ends of the pump-tube, and it forms the Water-WaysG G for a three- Way valve, H, having a seat, I, upon Which it 5o turns,and provided with openings i it, Op-

posite the valve-seat I a branch, L, enters the part F, having a shortseat vfor the valve at the points a c and giving said valve the necessary support. The plunger-rod D passes through an opening, I, inthecentral part ofthe 55 body of thesection F. No stuilingboxes are used,the Water-packing being all that is required. Even should the Waterescape between the plungerrod and the sides of the Wall through which itpasses, it will not affect the operation, since it readily leaks backthrough the freezing-hole, which is always above the three-Way valve.The valve H is operated by an arm, M, which has one end united with thespindle of the valve. By lifting the opposite end the valve may beturned so as to. cut off the current ot' water from the branch pipe Land direct it through the Water-ways G- G to the spout of the pump. Thisarm M may be operated bya rod, N, passing down through the platformorHoor, upon Which the pump stands, and pivotally connected With said arm,as at m.

In Fig. lv the plunger-rod is shown passing through the Waterways of theinterposed seetion-pipe and without packing-boxes. For all ordinaryconstructions this answers every purpose, and by operating the pump inthe usual manner Water may be delivered at the spout B, or by changingthe three-Way valve 8o II it may be directed through thebra-nch pipe Land carried to any desired point. W'hen it is desired, however, to forcethe Water to a point above the level of the pump, orto ob= tain a head7or -pressure upon the stream S5 issuing through the branch pipe, it maybe necessary to pack the plungeraod, and this I propose to accomplish byeither of the following constructions. Y

F, Figs. 2 and 3, represents the section-pipe 9o shown in Fig. l, having.the water-Ways G G and the bran ch pipe L, together With the three- Wayvalve II, having its seats formed in the manner already described.Instead, however, of casting the structure with a solid continuous bodyof metal between'the two Water-Ways, through which the plunger-rodpasses Without packing, as in Fig. l, I propose to pass the rod throughthe Walls d d, one or both of which may be provided with a suitablestufiing-box. Ioo

2 QEDLQH@ In the figures referred to I have shown one gland and box onlythrough which the rod passes placed in the lowerl wall. A convenientform of construction is to form the lower the section-pipe F isC-shaped,'the three-way valve H being seated in the center of the longupright arm. L represents the branch pipe, and

P I? the ends of the pumptube, between which the section F isinterposed, each extremity of the latter having a shortvertically-arranged head, It, one end of which receives the end of thepump-tube P, while into the other end is screwed a stuiiing-box, g. Thisbox is cupshaped, and has a female thread cut within to receive a gland,L, which closely surrounds thepiston-rod D. The end of said glandentering the box is concaved, as shown at m', whereby the packing in thebox will, as the gland is screwed down, be wedged or driven closelyagainst the rod, thereby making a perfectly-tight joint, and the outerends of the glands are cupped, as shown in said figure.

It will readily be seen that Vby this construction the pump may be usedas a forcepump at either the branch pipe or the spout I5.

The value and importance of this invention are evident. It is oftennecessary to carry water to different points, in manufacturingoperations, in farming and stock-raising, as well as in other callings.By my invention this may be accomplished without the expense of acomplete special apparatus, since the attachment may be applied to anyordinary pump at very small expense.

In Fig. 5 I have illustrated modiiied means for operating the three-wayvalve. In this example the cock II stands vertically in the section F,and has an annular head, a', for receiving the socketed end b of the rodc', the latter having a suitable handle, (l, at its upper end, locatedwithin convenient reach, which I arrangement is simple and efficient.

In most yard-pumps now manufactured the pump tube or barrel is madecontinuous and straight from end to end, and the plungera'od passesdirectly through the same. By my in vention I am enabled to apply thethree-way valve or cock to this style of pump without materialreconstruction of the tube or barrel rately-working structure, reducingthe cost of manufacture, and avoiding the employment of a separatedischarge-pipe leading from the pump tube or barrel to the three-wayvalve,

as usual. Further, the valve can be applied to any of the usualconstructions of pumps, and if attached to one style of pumpstandard itcan be changed to another style without extra fittings, and as theplunger-rod is inclosed within the pump-tube and the waterways of thevalve, the rod is not liable to become bent or injured, but is at alltimes retained in alignment with the tube and waterways.

Having thus described my invention, what I claim is- The combination,with a pump-tube,v of a three-.way valve or cock having a lateral cbranch pipe, and provided with two waterways arranged in alignment andintroduced into the pump-tube to form straight continuations thereof,and a plunger-rod passing directly through the pump-tube from its topportion, and also through both the aligned water-ways of the three-wayvalve'or cock, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
